This section describes the objects that developers use within DTC when developing resource managers.

Object	Description
DTC Proxy Core	Provides DTC proxy interfaces for creating transaction objects, transaction options objects, export objects, and resource manager objects.
Enlistment	Created each time a resource manager enlists in a transaction. DTC uses the enlistment object to determine which resource managers to involve in the two-phase commit process.
Export	Represents a connection between a resource manager proxy and a resource manager. The export object is used to propagate transactions between processes or systems.
Resource Manager	Created when a resource manager initially connects to a transaction manager.
Transaction	Represents the DTC transaction.
Transaction Options	Contains transaction attribute information, such as the time-out for the transaction and the transaction name.
Transaction Phase0 Enlistment	Notifies an application of a particular transaction that the client has initiated the transaction commit or abort but before the two-phase processing has been initiated.
Voter	Represents an application's vote for committing or aborting a distributed transaction.
XA Single-Pipe Resource Manager	Represents a XA resource manager based on the one-pipe coordination model implemented by the DTC XA transaction manager.
XA Single-Pipe Resource Manager Pseudo-Object	Represents a XA resource manager helper based on the one-pipe coordination model implemented by the DTC XA transaction manager.
XA Two-Pipe Resource Manager Pseudo-Object	Represents a XA resource manager based on the two-pipe coordination model implemented by the DTC XA transaction manager.
